usb: ums: add ums exit feature by ctrl+c or by detach usb cable
This patch allows exiting from UMS mode to u-boot prompt by detaching usb cable or by pressing ctrl+c. Add new config: CONFIG_USB_CABLE_CHECK. If defined then board file should provide function: usb_cable_connected() (include/usb.h) that return 1 if cable is connected and 0 otherwise. Changes v2: - add a note to the README Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Marek Vasut <marex@denx.de>
